Welcome to the Future of Fluid Power!
By DAN HELGERSON, CFPAI, CFPS, CFPMT, CFPECS, CFPSD After many years with little or no change in the components or approaches to the application of fluid power, some new ways of thinking and some new products are bursting onto the scene. Benefits of the New Products Digital pneumatics, Digital Displacement® pumps and motors, and smart […]
Case Study: Hundai Drives Ahead with Flexible and Efficient Control Valve Platform
By Edwin Harnischfeger, Senior Application Engineer Construction Machinery, Bosch Rexroth The decision to use the modular RS valve platform with similar equipment brings many advantages. The same modular technology for all machine types and performance classes not only simplifies engineering, but also documentation and service. At the same time, Hyundai benefits from even more precise […]
Case Study: Making an Electric Drive Hydraulic
By Murali Kailasam, Product Application Engineer, and Regis Jose, Senior Account Manager, Danfoss Power Solutions. FLSmidth, a multinational engineering company headquartered in Copenhagen with more than 10,000 employees in the mining, mineral, and cement industries, received a request from a coal mine in India for its feeder breaker machines. Feeder breakers are one of the […]
Perfect Proportion: Closed Loop Control for Mobile Applications
By Ben Dupre, Senior Technical Writer, HydraForce. Control for critical applications like autonomous steering has resulted in complex strategies to manage hysteresis, threshold, coil temperature, and other challenging variables in mobile hydraulics. The reliable control we’ve achieved was bought with much toil, including costly development and intensive tuning efforts to match the needed performance and […]
Vertical Integration: Electronic Load Sensing for Hydraulic Pumps
By Neil Skoog, CFPS, Project Developer, ERHCO. Load sense control of open circuit variable displacement piston pumps has contributed significantly to reducing energy consumption in hydraulic systems. This is especially true for mobile hydraulic systems that have widely varying load and speed requirements punctuated by periods of standby where no work is done. The known […]
Test Your Skills: The Application and Operation of Transducers
In closed loop control applications, it is necessary to convert some physical property into an electrical signal to provide a feedback signal to the amplifier. The components that carry out this conversion are known as transducers, and the ones most commonly encountered in electrohydraulic applications are pressure, flow, linear displacement, angular displacement, and angular velocity. […]
New Festo Products Include Ultracompact Cylinders
Festo recently introduced a number of new products, including a line of shorter and lighter pneumatic cylinders. ADN-S Festo released ADN-S, a line of ultracompact pneumatic cylinders for smaller footprint, lighter, and higher performing machines. Thanks to an innovative one-piece housing, ADN-S double-acting cylinders are 36% shorter and 20% lighter than similar actuators. Because […]
This Week at OTC: Bosch Rexroth Highlights Offshore and Marine Technologies
At the Offshore Technology Conference, which runs until Thursday at Houston’s NRG Park, Bosch Rexroth boasts the efficiency, safety, environmental stability, and connectivity of its offshore and marine offerings. Here’s a look at some of the products and technologies featured at Bosch Rexroth’s OTC booth. Subsea valve actuator: Visitors will be able to see and […]
Replace or Restore? Why You Should Retrofit that Aging Press
By Mike Kramer, Press Application Engineer, Bosch Rexroth One of the most productive and hardworking machines in the industry today is the extrusion press. With proper maintenance and life-cycle management, many extrusion presses operate productively for decades, often with their original hydraulic pumps, control valves, and other components. However, this longevity leads to persistent complications; […]
Bosch Rexroth Wins Hannover’s Hermes Award, Features Linear Drive
At the Hannover Messe trade show in Germany, Bosch Rexroth won the Hermes Award for its SVA R2 subsea valve actuator, the world’s first electrical actuator for controlling process valves underwater. The Hermes Award is Hannover Messe’s annual international technology prize. It recognizes outstanding products and solutions that have a particularly high level of technological […]
